IMPROVEMENT IN MAGAZINE HEATING-STOVES.

Specification forming part of Letters Patent No. 176,681 dated April 25, 1876; application filed January 3, 1876.

To-all whom it may concern:

Be it known that I, JULIUS F. QUIMBY, of

thecity of Troy, county. of Bensselaer, State of New York, have invented certain Improvement in Heating-Stoves; and I do hereby declares-that the following is a description thereof, ,reference being had to the accompanying drawings, forming a part of this speci: fication, in which- Figure l represents a perspective view of' the stove with parts broken away, and exposingaipartof theimprovements in this invention. Fig. 2 is atsectional elevation taken from-front to rear. Fig. 3 is a horizontal flue takenat line No. l in Fig. 2. Fig. 4 is a horizontal flue taken at line No. 2 in Fig. 2. Fig.

directly opposite. the rear of the combustionchamber and the u'pper'portion of the ascending flue at the rear of said descending flue, while the lower portions of both said flues may be transverse, the former to discharge into the, base-fines and the latterto draw from said base-tines to a suitable exit; second, to divide the inclosed space of the rear-projecting portion of the stove by afluestrip located about centrally in said space, and extending from side to side in the upper portion of the same, and in its lower portion extending from front to rear and transversely with the upper portion, with a twist intermediate between said upper and lower portions; third, to cause small streams of hot air, admitted to the combustion-chamber through theupper margin of the fire-pot, to be drawn in a horizontal direction over the hot firesurface and through the entire space of the combustionchamber, and the hot gases evolved from-the top surface of the burning coals to a descending flue or exit at the extreme rear of the stove ;v fourth, to render the exit-flue ring changeable from 'a; horizontal to a: vertical, and the reverse, and close the opening not occupied by the exit-flue ring, whether it be the horizontal or vertical opening notrequired to'be used.

To enable others skilled in-the art to make and use my invention,I will proceed to describe it in reference to the drawings and the letters of reference marked thereon, the same letters indicating like parts.

In the drawings, A represents the hollow base of the stove containing hotgas-circulatin g chambers 00 and b. B is the ash-pit chamber, provided with the usual door or doors for access to the interior of the same, and draftdampers for the admission of air to support combustion. O is the super-draft chamber, located above the ash-ring and surrounding the fire-pot, and is provided with doors set with mica or equivalent substance to permit illumination. '1) is the fire-pot. Eis the grate. F is thecombustion-chamber, in which the gases evolved from the top surface of the incandescent fuel are burned. G is the fuel maga- .zinc or reservoir. H is the descending flue leading from the rear of the combustiontchamher down into the hot-gas-circulating chamber 0t. J is the ascending flue leading from the hot-gas chamber b of the base tothe exit K. All the said parts are old, and,as parts, form no portion of this invention. The rear portion of the outer casing or walls of the ash-chamber, super-draft chamber, and a portion of the walls of the combustion-chamber, are projected back to" inclose a space at the rear for the descending and ascending. flues Hand J. The said space extends from the exit K vertically down'to the hollow base A, and is divided by the flue-strip S, or aggregate sections of flue-strips, to form with the walls of the said-rear projecting cas'in g the said flues. The'flue-strip S, or the sectionscomposing the same, commences at the base of the head L of; the space containing the descending and ascending flues, and at a distance below the lower side of the short horizontal flue M leading from the combustion-chamher to the said flue-space or exit, as at e, from which the damper d swings, as shown in Figs. 1 and 2. At the damper d the flue-strip S divides the flue-space contained in the rear extention of the casing, by running from side to side, as in Figs. 5 and 6, so that the descendin g flue, in its breadth, may extend from one lateral side wall of said casing to the other, and face the fire-pot, or the rear ashchamber wall-plate h, in its full width. The said flue-strip is extended down in a plain vertical line to near or at line No. 2, Fig. 2, where it is made with a quarter twist, s, as shown in Figs. 1, 2, and 4, which twist turns the lower terminating end of the said fluestrip at right angles. with the direction of its horizontal line above, at the damper d, and throws the one in a transverse direction of width with the other, so that while the direc-- tion of the width of the upper end of said flue-strip above will .be relatively parallel with a line, 5, tangent with the combustionchamber, the lower end will be relatively radial with the same.

It will be readily seen by thus dividing the flue-space by the flue-strip S, having each of its opposite ends in their extension of width transverse to the other, with the twist s intermediate between, that the said space is divided into two flues of about equal capacity, in which each flue may have an easy curve of surface from the said flue-strip to lead the hot products in a sheet form of volume from the combustion-chamber to a more square form of the same, without being in the least liable to choking. In the front wall of the descending flue H, separating the same from the superdraft chamber (3, is located the check-damper N operated by the rod n. The upper-margin edge of the fire-pot is provided with small perforations 222, which communicate from the super-draft chamber 0 to the combustion chamber F, where the hot andinflammable gases are evolved from the massed fuel in combustion in the fire-pot. The said perforations admit air from the said super-draft chamber after it has been received within and highly heated by the radiant heat from the inclosed fire-pot, and discharges the same in small cur; rents or streams into the. said combustionchamber to mingle with the hot gases evolved from the top surface of the burning fuel, and contribute to the combustion of the said gases, which otherwise would escape unconsumed to the exit or to the descendingflue.

It will be readily seen that, as the exit or the descending flue at the rear draws the hot gases away from the front and side mica win- (lows, and the highly-heated air admitted from the super-draft chamber to the combustion-chamber is introduced at the top margin of the fire-pot, and is also drawn by the draft toward the rear, the air thus introduced in small streams and in a highly-heated state-to the said hot and inflammable gases, may cause their ignition when passing over the top surface of the fire-toward the exit or descending ing from the mingling of the highly-heated and expanded air from the marginal perforations z with the inflammable gases, and the draft of the resulting hotter products of combustion to the descending flue into the base, the said base may become more highly heated in its side walls than they would were the inflammable gases permitted to be drawn from the combustionchamber without being ignited or inflamed by the heated air from the super-draft chamber.

The damper d, when turned as show in" Fig. 1, permits the hot gases to pass dir' ct to the exit K, and when turned as shown by full lines in Fig. 2, causes the draft to be reverted into the base by passing down the descending flue H into the chamber a of the base, thence forward and into the chamber 1), as indicated by arrows in Fig. 2, and thence up the ascending flue to the exit.

The exit-flue K consists of a removable piece made in the form of apipe-collar and capable of interchangeable placement with the stopplate K, at either the top opening .90, as in Figs. 1, 6, and 7, or with the rear-opening :20, in Figs. 2, 6, and 7. The stop-plate K consists of a plate corresponding in its circumferential form with that of the exit-flue K.

The openings on and w are each provided with lugs or cars it provided with bolt-holes 22, which correspond in their relative location with their respective openings, one with the other. The removable and interchangeable exit-flue and stop-plate are each provided with bolt-holes 3 3, corresponding with boltholes 2 2, with openings 00 w, the said holes being made in the stop-plate itself at its ends, and those with the exit-flame made in lugs or ears attached with the same, as shown in Fig. 7.

By thus constructing the openings .10 and :0 with the corresponding circumferential forms, and with bolt-holes 2 2 corresponding with the circumferential forms of the exit-flue K and stop-plate K and their bolt-holes 3 3, the said exit-flue may fit either opening as or ac, and the said stop-plate may also fit either of the said openings.

The advantageous results produced by this part of my improvements are these: the exitflue may be employed with the top openingm when the smoke-pipe is to be extended vertically, while the stop-plate maybe made to close the rear opening 00, or the exit-flue may be transferred to the rear opening :0 and permanently secured to the same when the smoke-pipe is to lead horizontally from the stove, while the stop-plate may be made to nacs 3 Vstrip S, made either in a single piece or in sections, and extending vertically from damper (1 to the bottom of chambersct and b, with their upper portions relatively as shown, and their lower portions. relatively transverse to said upper portions, substantially'as set forth; 2. The combination, with the space inclosed by the rear extension of the stove, and occupied by descending and ascending fines, of

4 the flue-strip S, composed of either a single piece or sections, and dividing said space by the lateral extension of its width from side to side, in its upper portion, and from front to rear or transversely in its lower portion, with the twist s between said upper and'lower portions, substantially as set forth.

3. The combination, with the horizontal top opening as over the space containing the descending and ascending fines, and the vertical opening :0 at rear of the head of said space, provided each with'lugs u and boltholes 2 2, of the exit-flue ring K and stopplate K, each provided with bolt-holes 3 3, A

and capable of an interchange of attachment with said openings ac and 00, substantially asand for the purpose set forth.
